Natural Hair Color

Natural Hair Color:

To understand how hair color formulas react with natural hair, a look at the hair’s natural levels of color need to be understood and recognized.

The medulla: This is a tubular

core found in the center of the hair shaft. Medulla is not found in all

hair and has no known function.

The services you perform are not

concerned with the medulla.

The cuticle: This is a colorless, translucent casing over the hair

shaft. It consists of overlapping scales containing no natural color.

The cortex: This part contains the great bulk of melanin (the natural pigment found in hair and skin), lodged between its fibers.

The hair’s structure is made up of:

Color is formed in the cortex of the hair by melanocytes that produce

three types of pigment (melanin):

💫Eumelanin (granular melanin)

Eumelanin (natural black to red)

pigment (sometimes called "granular”) is larger in size than diffused pigment, so fewer actual pigment granules are needed to color a hair shaft. Because there

are fewer of them, eumelanin pigment is more easily and quicklyremoved from the hair shaft.

💫Pheomelanin (diffused melanin)

Pheomelanin (natural red to pale yellow) pigment (sometimes

called “diffused”) is much smallerthan eumelanin pigments. There

are many more yellow and red

than black and brown pigments

in a single hair shaft. This makes

them more difficult to remove.

💫Mixed Melanin (when both types

are present in one melanin granule)

💫💫In addition, canities is the

absence of pigment in hair.

White or grey hair is found on

guests whose hair has stopped

producing melanin due to age

or congenital conditions.

The amount of non pigmented

hair on a guest’s head is usually described in percentages: 25%, 50%, or 75%.
